Could anyone tell me what thread the 8 mounting bolts are for the sprocket on a Bantam/Cub hub? They are 1/4 diameter but not sure if they are BSF or cycle thread - or whether there is any difference! Thanks

I sort of like the second one but that first one is bloody awful. It doesn't even look like a classic British trials bike, you might as well just move onto twinshocks. What makes it worse is that a nice pre unit Triumph has died to create it!!

That's a C15 head. I can't see any kinking or flattening of the pipes and I can't imagine the oil not being able to flow up that little rise if it's just managed to get all the way from the bottom of the engine. Have you got a copy of Rupert Ratio? Might give you some ideas. If not then try asking on b50.org forum, some very knowledgable BSA unit single chaps there.

Barry, how is the restoration going?! I think your idea for doing it is about right. You've got to get rid of that rust or it will get worse so once you start you've got to do it all. But as you say you don't need to make it concourse. I'm restoring my C15T and am trying to keep it very much in line with how it might have been as a competition bike in the sixties. No powder coating for me, I'm hand painting the frame in coach enamel. It looks smart but not over done. I was quite interested to see your bike because it's given me an idea about what colour I'm going to paint the tank. It's got a period alloy trials tank on it which I'm going to do two tone, silver at the back and another colour at the front. Looking at your original bike I'm now thinking that the blue on yours might look quite good. I'm guessing its Nutley Blue which was a BSA colour on many bikes in the 60's. Anyway, it would be good to hear the old Beesa is doing!

Thanks chaps, I'm erring on the side of leave as is at the moment. I'm just not sure enough that its not supposed to be like that to start altering it. I know I can get the desired clearance as its been ok for years. Interested to hear any more suggestions or advice!

Hello, my first post on here but been lurking around the forum for a while. I'm in the middle of restoring my 1962 C15T and have come across a bit of a problem. The rear wheel is quite a bit out of line with the main frame loop and after a lot of checking and measuring it seems to be that the whole swinging arm is out of line. The lug that the swinging arm spindle goes through is twisted over to the left of the bike compared with the bottom frame tube. I've found a thread on here with someone with a similar problem, in fact it looks exactly the same in the photo. Here is a link to it: http://www.trialscentral.com/forums/topic/27793-c15-frame-alignment/ All the brazing seems sound and it looks to that it was made like that, maybe BSA's way of getting chain clearance for the wider trials tyre than on a standard bike. Can anyone confirm if that is the case? The rear subframe obviously is also out of line but when the bike is all built up it looks fine as the wheel sits equally between the shocks etc. I've owned and used the bike for 25 years and although I knew the rear wheel was a bit out of line it's always been ok. It's not road registered so getting it through the mot was never a problem. I'm now thinking of getting it registered so would now need to get it mot'd which might be a problem if the wheels are out of line. So my options are: Leave it as is and see if it passes an mot, if not I'll just not bother registering it and keep using it as it is - it rides fine. Use spacers at the rear wheel to try and get it closer to line up. This would mean the wheel was then out of line with the subframe though. Get the frame lug moved in line by re brazing it. Not something I could do myself and I'm not even sure it should be done! Any thoughts would be greatly appreciated!! Cheers
